XL1682 is a high-performance AC/DC universal input primary-side regulation power factor controller for LED drive applications. The device uses pulse frequency modulation (PFM) technology to regulate the output current while achieving high power factor and low THD.
XL1682 provides accurate constant current (CC) regulation while removing the optocoupler and secondary control circuit. The need for loop compensation circuit is eliminated while maintaining stability. XL1682 achieves good regulation and high efficiency while meeting the requirements of IEC61000-3-2 harmonic standards.
XL1682 features low start-up current, low operating current and high efficiency. It also has rich protection functions, including overvoltage, short circuit, overcurrent protection, etc.
SOP-8 package.
